Supplanter
Kuba is the Polish diminutive form of Jakub, which is the Polish equivalent of Jacob or James. It shares the etymological root meaning 'to follow' or 'to supplant', referring to the biblical story of Jacob. While used as a nickname in Poland, it is increasingly used as a standalone given name in international contexts.
